Headache and rhinosinusitis are 2 of the most common conditions seen in clinical practice. In general, chronic and disabling headaches, especially if migraine features are present, are not due to sinus abnormalities. In suspected cases of bacterial sinusitis, computed tomography and magnetic resonance imaging are both effective in demonstrating the ...

Pyomyositis is a bacterial infection of skeletal muscle that often results in deep intramuscular abscesses. The absence of external dermatologic manifestations in the early stages of pyomyositis makes this a challenging diagnosis. In addition, physical examination findings can be difficult to distinguish from more common processes, such as soft-tissue cellulitis. ...

As a facultative anaerobe, Vibrio cholerae can grow by anaerobic respiration. Production of cholera toxin (CT), a major virulence factor of V. cholerae, is highly promoted during anaerobic growth using trimethylamine N-oxide (TMAO) as an alternative electron acceptor. Here, we investigated the molecular mechanisms of TMAO-stimulated CT production and uncovered ...
